关于#django#的问题：试了几种方法也不行，测试链接也没问题(开发工具-pycharm)

试了几种方法也不行，谁能告诉我这么解决这个问题，密码没问题，测试链接也没问题，一用起来就出问题

用户名应该是大写USER，密码应该是大写PASSWORD

• 这有个类似的问题, 你可以参考下: https://ask.csdn.net/questions/7417498
• 这篇博客也不错, 你可以看下pycharm中安装django遇到的问题
• 除此之外, 这篇博客: Django框架（二）--使用PyCharm打开启动，简单编写，正则表达式，路由匹配中的 三、配置文件的介绍 部分也许能够解决你的问题, 你可以仔细阅读以下内容或跳转源博客中阅读:
